Return expected source and semantic failures from the runtime input owner as tagged Results. Bind source schema validation to concrete schemas, preserve nested active-capture paths, and let unexpected interpretation and derivation failures reach the adapter boundary.
Remove broad protocol-error wrappers, duplicate active identity validation, and redundant JSON result parsing. Migrate parsed-fact consumers and retain CLI/MCP contracts. Relevant source and public-boundary tests pass; six injected implementation-fault controls fail on the prior revision. Live Electron behavior was not exercised.
Preserve invalid V8 script events as unavailable protocol data instead of merging them into target-policy exclusions. Keep independent producer counts, original Evidence, and existing target authority.
Validated with 90 focused Linux tests, real Node Inspector CLI/MCP captures, complete static/architecture checks, and current-head automated review/CI.
Fixes#4376.
* feat(browser): attach passive tools to browsers without HTTP discovery
Accept a literal loopback browser WebSocket,
ws://127.0.0.1:PORT/devtools/browser/ID, as the cdp_endpoint of the six
passive browser tools. Discovery then reads Browser.getVersion and
Target.getTargets over that socket, and the target session adopts the
same socket, so a browser that asks for consent per connection prompts
once per call.
The socket identifier gates access, so Evidence records the endpoint as
ws://127.0.0.1:PORT/devtools/browser/[REDACTED], and runtime
reconciliation accepts that recorded form. HTTP endpoints and their
Evidence are unchanged. Electron, web runtime, scenario and Inspector
endpoints stay HTTP-only.

* test(browser): match browser-socket captures against HTTP discovery
Check in the real Chrome lane that DevToolsActivePort names the same
browser socket as /json/version, and that inspecting the selected page
through that socket leaves DOM structure and scripts unchanged compared
with an inspection through HTTP discovery.
Refs #2288
* fix(browser): bound browser-socket handshake and report discovery timeouts
Run the browser-socket WebSocket handshake and both discovery commands
under one discovery deadline, so a port that accepts the connection but
never completes the upgrade times out instead of waiting forever.
Report a reached deadline as a timeout without carrying the internal
abort as its cause, so CLI and MCP project provider_timeout rather than
cancelled. Caller cancellation is still reported as cancelled.
Refs #2288
Keep omitted discovery attachment state as null through Node, browser, Electron, and reconciliation evidence. Report the uncertainty while retaining Node observation unless discovery explicitly marks the target attached. Reject worker TargetInfo records missing the required boolean with partial coverage.
Validate omitted and explicit states through provider, CLI, and MCP boundaries and real Node 24 Inspector workflows. Consolidate Electron regression coverage into the existing list-and-inspect workflow.
BREAKING CHANGE: attached fields in JavaScript runtime, browser, and Electron target discovery and inspection results may be null when discovery does not report attachment state.
